Look out incumbents and look out fellow coal-country Democrat Mark Critz.

Alan Mollohan -- as we've warned here at Early Returns -- got crushed last night in the West Virginia primary, getting beat out by conservative Democrat Mike Oliverio. Here's the WashPost's Chris Cillizza:

Mollohan hadn't faced a serious primary fight in more than a decade and was seen in some circles as unbeatable, given that the state's 1st Congressional District seat had been in his family since 1968. (His father held it for seven terms before he won it.)

But state Sen. Mike Oliverio ran hard against Mollohan's entrenched-incumbent status and made much of the lingering whiff of ethics problems that dogged the congressman for years.

With 98 percent of precincts reporting, Oliverio had 56 percent of the vote to Mollohan's 44 percent. In November, he will face former state delegate David McKinley, who won the Republican primary Tuesday night.

As CQ Politics noted yesterday, Oliverio attacked Mollohan over ethics in a similar way (in a similar part of the country) to how PA-12 Republican Tim Burns is going after Critz. (Critz is still up by 6 points in the race, they note.)

Here's coverage from the Wheeling News-Register and the Charleston State-Journal.
